While I was an LEO for 20-1/2 years, I think I went through at least 10 different guns, including my actual duty gun at one point, trying to find the right gun that I would carry religiously every time I went out of the house when I was off duty. The guns ranged from a 9mm Sig P226, Ruger P95, S&W model 19 4", Glock 23, and a S&W 642. Obviously I skipped over a few others not really worth mentioning, but I concentrated on the more "respected" calibers of .38 spl/.357, 9mm, & .40 S&W.
Every one of those guns ended up staying home because to me they were too big/cumbersome/uncomfortable to carry, including that 642 Airweight if you can believe that---it was still just a little too big. I tried OWB, IWB, pocket holsters (for the 642) but to no avail. In my latter years of law enforcement I was so "over it" that it got to the point I had no interest in guns, sold off what I had, regrettably (oh to have that model 19 and P95 back----I loved those guns) and my shooting was limited to 4 times a year at qualification. I am ashamed now to say that I had no interest in carrying off duty, probably because I gave up trying to find the right gun and really wasn't interested in continuing the search because my interest in guns was zero.
About a year and a half ago, after being retired for about 3-1/2 years, my interest in guns was resurrected, and I sought to get my LEOSA permit. I wanted to be serious about what I knew I would carry every day, as my tastes for what I thought was uncomfortable to carry had not changed. Small in size as they are, I found 9mm guns like the Shield and Ruger LC9 to be not quite small enough (yes I admit I am picky to the point of being psychotic). I picked up an M&P Bodyguard and Ruger LCP and knew I found what I had been looking for, choosing the S&W.
The .380 has resided in my pocket every time I leave the house, go to work, go out for the evening, etc., etc. I carry it to the point that it is a habit for me now. I do take my .40 Shield out for a car ride when I'm going to Dairy Queen or someplace else where I know I won't be leaving the car. I am confident carrying the .380, made myself proficient in its use and I'll never look back.
I have the utmost respect for many people that are willing and able to carry compact .45's, Shields, snubs, etc. and have no qualms about their size and consider them comfortable guns to carry all day long. I wish I did find guns such as these comfortable to carry but I just don't---it's all a matter of personal preference. If it's not comfortable I'm not carrying it.
I would like to think that if I was in a somewhat crowded establishment, and the only 2 people in the place armed were me (with my .380) and someone else who carried a 9mm or larger caliber sidearm because that person felt the .380 was SO inadequate, and something went down, that other armed citizen would thank God someone else was at least carrying, and wouldn't care if the other's gun was a .22, a .380, or anything else.
